We're looking for an experienced engineer to join our small but mighty remote-only company. Our software powers the production Kubernetes infrastructure of companies around the world, and you'll work alongside some of the world's best engineers and on some of the world's most interesting distributed systems to accomplish our ambitious mission.

As a Linkerd engineer, you'll be a key member of our small (20 person) team. You will own extending the Linkerd proxy layer to run natively on Windows, wrapping a network application to handle its inbound and outbound traffic, and delivering a production-ready solution for our customers. The role will evolve to include a combination of maintaining Linkerd’s Windows support and other more general Linkerd proxy use cases on Linux and Kubernetes, in the Rust and Go languages. You will learn an incredible amount and you'll have the opportunity to make a profound impact not just on Buoyant but on people around the world.

Buoyant is not a peace-time operation. We compete every day against behemoths with infinite resources, time, and people. This role calls for an experienced, strongly self-motivated person who is unafraid to work across a wide variety of languages and environments; who can handle ambiguity, complexity, and fast-moving requirements; and who can demonstrate ownership, a bias to action, and the ability to “ship it”. You’ll work as part of a team of world-class builders who value collaboration, pragmatism, and low-ego teamwork.

We are a remote-only company that relies heavily on writing to communicate ideas. This role requires excellent written communication skills.

  • Ensure performance, correctness, and maintainability of Linkerd across multiple requirements including: high traffic load, different protocols, resource constraints, and other product features

  • Develop your project workflow for CI/CD repeatability and for maintainability by others

Qualifications

To excel in this role, you should possess the following qualifications:

  • 3 or more years developing system-level software for Microsoft Windows operating systems, including Windows Kernel Mode Development
